Description

Technical Field

[0001] This disclosure relates to the field of flower spraying machine technology, and in particular to a swingable flower spraying machine. Background Technology

[0002] Stage fireworks machines are special effects equipment commonly used in stage performances and celebrations. Current stage fireworks machines work by heating the spray material and then blowing the material out when it reaches its ignition point using a fan, creating the stage effect of shooting fireworks.

[0003] However, because current stage spraying machines blow the spraying material directly out using a fan, the spraying angle cannot be controlled. The direction the fan blows is the direction of the spray, resulting in a relatively monotonous stage effect. Utility Model Content

[0023] Example

[0024] like Figure 1-2As shown, this embodiment provides a swingable sprayer, including a mounting frame 1. The mounting frame 1 consists of a base plate and multiple mounting plates vertically fixed to the base plate. A turbine fan 2 is bolted to one side of the mounting frame 1. A hollow shaft 3 is rotatably connected to the middle of the mounting frame 1 via a bearing seat 31. The bearing seat 31 is a bearing housing, and a bearing is embedded in the bearing seat 31. The hollow shaft 3 passes through the bearing seat 31, allowing it to be rotatably connected to the mounting frame 1. The blowing end of the turbine fan 2 is connected to one end of the hollow shaft 3. A hollow bend 4 is bolted to the other end of the hollow shaft 3. A spray pipe 5 is bolted to the end of the hollow bend 4 away from the hollow shaft 3. The output end of the spray pipe 5... The mounting bracket is positioned upwards, with a drive mechanism located below the hollow shaft 3. The drive mechanism drives the hollow shaft 3 to rotate. A feeding device is located on the side of the ejection pipe 5 away from the turbine fan 2. The output end of the feeding device is connected to the bottom of the ejection pipe 5. The feeding device is used to transport metal powder with a low ignition point to the ejection pipe 5. During the transportation process, the metal powder is heated to the ignition point. The metal powder with the ignition point is blown out of the ejection pipe 5 by the wind force of the turbine fan 2, forming a firework effect. During the ejection process, the hollow shaft 3 is driven to rotate by the drive mechanism, thereby causing the hollow curved pipe 4 and the ejection pipe 5 to swing synchronously, thus forming a unique firework visual effect.

[0025] Specifically, the drive mechanism includes a stepper motor 61 bolted to the bottom of the mounting bracket 1. The output shaft of the stepper motor 61 is keyed to a main synchronous pulley 62. A driven synchronous pulley 63 is fixedly connected to the outside of the hollow shaft 3. The main synchronous pulley 62 and the driven synchronous pulley 63 are connected by a synchronous belt 64. Both ends of the hollow shaft 3 are rotatably connected to the mounting bracket 1 via bearing seats 31. The drive motor drives the main synchronous pulley 62 to rotate, which in turn drives the driven synchronous pulley 63 to rotate, thereby causing the hollow shaft 3 to rotate. The rotation of the hollow shaft 3, along with the synchronous belt 64, causes the hollow curved tube 4 and the ejection tube 5 to oscillate, thus achieving different visual effects of fireworks.

[0026] Furthermore, an encoder 65 is fixedly connected to the middle of the mounting bracket 1, and the encoder 65 is connected to the synchronous belt 64. The encoder 65 is electrically connected to the stepper motor 61, and the encoder 65 detects the rotation angle of the stepper motor 61, thereby controlling the swing amplitude of the nozzle 5.

[0027] Specifically, the feeding device includes a storage bin 7 bolted to the mounting frame 1 and a feeding mechanism disposed at the bottom of the storage bin 7. The top of the storage bin 7 has a feeding port, and the bottom of the storage bin 7 has a discharging channel. The feeding mechanism includes a DC motor 81 bolted to the mounting frame 1. The output shaft of the DC motor 81 is keyed to a main sprocket 82. The main sprocket 82 is driven to a driven sprocket 83 via a chain 84. The driven sprocket 83 is fixedly connected to a conveying screw 85. The bottom of the storage bin 7 is fixedly connected to a feeding sleeve 86. The feeding sleeve 86 and the discharging channel at the bottom of the storage bin 7 are connected in a continuous manner. The conveying screw 85 passes through the feeding sleeve 86. The side of the ejector pipe 5 has a feed inlet, and one end of the feeding sleeve 86 passes through the feed inlet. Metal powder is added to the storage bin 7 and enters the feeding sleeve 86 by gravity. The DC motor 81 drives the main sprocket 82 to rotate, which in turn drives the slave sprocket 83 to rotate, thereby driving the conveying screw 85 to rotate. The rotation of the conveying screw 85 causes the metal powder in the feeding sleeve 86 to move forward and enter the feed inlet, thus entering the nozzle 5. Through the blowing action of the turbine fan 2, the metal powder is sprayed out from the top opening of the nozzle 5, thus forming a firework effect.

[0028] Furthermore, a heating core is embedded inside the feeding sleeve 86. The heating core is an electric heating wire or electric heating plate in the prior art. The heating core embedded in the feeding sleeve 86 generates heat, thereby heating the feeding sleeve 86. As the metal powder is fed through the feeding sleeve 86, it is gradually heated to the ignition point and then enters the ejection pipe 5, so that the ejected metal powder burns to form a fireworks effect.

[0029] In one embodiment, a stirring mechanism is also included. The stirring mechanism includes a stirring motor 91 bolted to the side of the storage silo 7. The output shaft of the stirring motor is fixedly connected to a stirring rod 92, which penetrates the storage silo 7 and extends into its interior. To prevent metal powder from clogging the bottom of the storage silo 7, a stirring mechanism is used to accelerate the feeding speed and improve the smoothness of the feeding process. The stirring motor 91 drives the stirring rod 92 to rotate, thereby rapidly feeding the metal powder and preventing clogging.

[0030] Furthermore, the hollow bend 4 is a U-shaped tubular structure. The U-shaped structure allows the wind force of the turbine fan 2 to turn, blowing the metal powder upwards.

[0031] Furthermore, it also includes a cooling fan 10, which is fixedly connected to the bottom of the mounting bracket 1. The cooling fan 10 accelerates airflow and improves heat dissipation efficiency.

[0032] The working principle of this invention is as follows: Metal powder is added to the storage bin 7. After entering the feeding sleeve 86, the metal powder is driven by the DC motor 81 to rotate the conveying screw 85, which conveys the metal powder forward. During the conveying process, the metal powder is heated by the heating core to reach its ignition point. Once the metal powder reaches its ignition point, it enters the firing tube 5. At the same time as starting the DC motor 81, the turbine fan 2 is also started. After the metal powder enters the firing tube 5, the wind force of the turbine fan 2 blows the metal powder that has reached its ignition point out, forming a pyrotechnic effect. Furthermore, to change the angle of the pyrotechnic eruption, the stepper motor 61 drives the main synchronous wheel 62 to rotate, which in turn drives the slave synchronous wheel 63 to rotate, thereby driving the hollow shaft 3 to rotate. The rotation of the hollow shaft 3 synchronously drives the hollow curved tube 4 and the firing tube 5 to swing, thus achieving different visual effects of pyrotechnics.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
